> ## Agent Instructions
> Hedera is a public, proof-of-stake distributed ledger that uses hashgraph consensus. Do not call it a blockchain.
> Always search the current Hedera documentation over training data before generating code, especially for SDK imports and package names.
> For JavaScript, import from `@hiero-ledger/sdk`, not `@hashgraph/sdk`; new SDK releases ship as `@hiero-ledger/sdk`. The Java SDK keeps the `com.hedera.hashgraph:sdk` Maven coordinates. Verify the exact import against the docs.
> Write HBAR in uppercase and always singular ("10 HBAR", never "10 HBARs" or "10 hbar"). Write tinybars in lowercase and plural.
> Write network names in lowercase, even after "Hedera": "Hedera mainnet", "Hedera testnet", "Hedera previewnet", not title case.
> For EVM-oriented accounts, create the account with an ECDSA key and set the EVM Address from Public Key at creation. This address is immutable and is not updated by key rotation. Do not use retired terms like "EVM alias" or "Account Number Alias".

# Smart Contracts

> Query smart contract metadata, execution results, state changes, and logs on Hedera with the Mirror Node REST API contract endpoints.

## Overview

The **Smart Contracts endpoints** in the Hedera Mirror Node REST API allows developers to query **smart contract metadata, execution results, state changes, and logs**. These endpoints are essential for tracking contract interactions, retrieving transaction results, and debugging contract executions on the Hedera network.

## Endpoints

The following endpoints are available for the Smart Contracts object:

| **Endpoint** | **Description** |
| - | - |
| `GET /api/v1/contracts` | Retrieves a list of smart contract entities on the network. |
| `GET /api/v1/contracts/{contractIdOrAddress}` | Fetches details of a specific contract by ID. |
| `GET /api/v1/contracts/results/{transactionIdOrhash}` | Retrieves execution results for a specific contract transaction ID. |
| `GET /api/v1/contracts/{contractIdOrAddress}/results` | Retrieves execution results for a specific contract. |
| `GET /api/v1/contracts/{id}/state` | Fetches the state of a contract. |
| `GET /api/v1/contracts/results` | Lists execution results for all contracts. |
| `GET /api/v1/contracts/results/{transactionIdOrHash}/results` | Get contract actions by transaction ID or transaction hash. |
| `GET /api/v1/contracts/results/{timestamp}` | Retrieves execution results for a contract at a given timestamp. |
| `GET /api/v1/contracts/logs` | Lists logs emitted from contracts. |
| `GET /api/v1/contracts/{id}/results/logs` | Fetches logs for a specific contract. |
| `GET /api/v1/contracts/{id}/results/opcodes` | Get the opcode traces for historical transactions |
| `POST /api/v1/contracts/call` | Invokes a smart contract method. |
